UNITED LUDWIK TROJAN, OF HAMTBAMCK, MICHIGAN.

ROCKER.

Application filed. June 30, 1921. Serial No. 481,541.

To all whom it may concern:

Be it known that I, LUDWIK TROJAN, a citizen of Poland, residing at Hamtramck, in the county of Wayne and State of Michigan, have invented certain new and useful lmprovements in vRockers, of which the following is a specification.

This invention relates to improvements in fan actuating mechanism and has for its principal object to provide a. device adapted for attachment to an ordinary rocking chair whereby the rocking action will be converted into rotary motion for actuating a fan or the like.

Another object of the invention resides in the provision of a fan so located in the chair back as to cool the occupant when the chair is in motion.

With these and other objects in view the invention consists in the novel construction, combination and arrangement of parts which will be fully set forth in the following specification, and illustrated in the accompanying drawing, in which,

Figure 1 is a side View of a rocking chair showing this improved fan actuating mechanism attached thereto and illustrating a portion 01' the chair back in section,

Figure 2 is a. rear view of the device, and

Figure 3 is a detail of the tan and its supporting means.

Referring to the drawings in detail, the numeral designates a rocking chair frame comprising the seat portion 11 from which the legs 12 extend and a back-13 is supported by a pair of uprights let which extend upwardly from the rear side of the seat portion 11. Secured to the lower ends of the legs 12 are rockers 15 which rest on the rabbetted portions of the side bars 16 of the base 17. These side bars are held in spaced parallel relation by the transversely extending bars 18 and 19 arranged at the front and rear ends of the bars 16. In order to hold the chair on the base and against accidental displacement a. pair of toggles 20 are connected between the rockers'15 and the side bars 16.

Pivota-lly connected as at 21 to a transversely extending bar below the seat frame 11 is a link 22, the opposite end of which is pivotally' connected to a link 23 having its end pivoted as at 2 1 to a bracket arranged centrally oi": the bar 19. A longitudinal slot 25 is formed in the link 22 and slidably receives a pin extending through the bifurcated lower end of a rod 26 mounted for slidable movement on the chair back. Secured to the upper end of the rod 26 is a longitudinally slotted rack bar 27 mounted for sliding movement on the pivot pin of a belt wheel 28 provided on its outer side with a pinion 29.

As shown in Figure 2 the rack bar 27 is provided on opposite side edges with teeth for meshing engagement with segments 30 and 31 respectively, and these segments are pivoted concentrically with the gears 32 and 38 provided with oppositely arranged ratchets 3 1 and 35 for cooperation with the pawls 36 and 87 carried by the segments 30 and 81 respectively.

Formed in the chair back 13 near its-upper end, is an opening for the reception of the fan supporting frame 38 which comprises a ring having a series of spaced horizontally arranged bars 39 in the rear of which the "fan 40 is rotatably mounted. A

pulley 4:1 is secured to the fan shaft and a belt 42 extends around'the pulley wheel 28 and pulley 41 so that when the wheel is rotated the fan will beset in mot-ion.

In operation it will be seen that as the chair is rocked, the rack bar 27 will reciprocate, causing the, segments 30 and 31 to oscillate. During the upstroke the pawl 36 will engage and drive the ratchet 3 1 and its associated mechanism while the pawl 37 will ride over the ratchet 35. The opposite operation takes place upon the downstroke so that a continuous rotary motion is imparted to the pulley wheel 28 and its associated mechanism, thus driving the fan.

While in the foregoing there has been shown and described the preiererd embodiment of this invention, it is to be understood that certain minor changes, in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What is claimed is The combination with arocking chair and a stationary base, of links connecting said chair and base, a bar slidably engaged to the back '0'? said chair reciprocated by said links, gear trains actuated by said bar, and means associated with said gear trains for continuously rotating said fan when said chair is. rocked.

In witness whereof I afiix my signature.

LUDWIK TROJAN.
